We have a 2012 Honda Civic with 30,000k miles. I have changed the oil every 5k. miles. I just got transferred and now work about 70 miles(round trip) from home. There is traffic some of the ways so there is some of that kind of driving. Our money, like many, is tight and we really want to keep this car going for as long as possible and with the least amount of problems. Can anyone suggest some things that should be done to the car at certain intervals or some tips. Is doing just what the manual suggests enough? Thanks you very much.
